Unclear MCP error

[jcubic]

Description

When MCP return an error, there is a cryptic error. You have no idea which MCP is throwing an error. And it disappears so fast that you can't even copy the error message to report a bug.

OpenCode version

0.15.31

Steps to reproduce

This is my config:

{
  "$schema": "https://opencode.ai/config.json",
  "keybinds": {
    "session_child_cycle": "none",
    "session_child_cycle_reverse": "none"

This issue might be a duplicate of existing issues. Please check:

• MCPClientError: Attempted to send a request from a closed client #1878: User reports similar problem - "How do I know which one from looking at the error?" when getting MCP errors, asking for better error source identification
• socket connection was closed unexpectedly. From more information, pass verbose: true in the second argument to fetch #3511: Reports MCP error messages that don't clearly indicate which server is failing ("socket connection was closed unexpectedly")
• Issue with MCP and config #1720: Another case of cryptic MCP errors with insufficient debugging information

Feel free to ignore if none of these address your specific case.

luckily context7 api keys arent that sensitive but you should prolly delete that key and make a new one

@jcubic I think it may be more clear if you update to latest, we are going to upgrade all v0 users soon, rn about 2/3rds of people are on v1.

You can do:

opencode upgrade 1.0.68

Oh, it didn't update automatically, like it use to.

Yeah what i was saying is we intentionally havent auto updated all the v0 users yet
